Question

So sánh :

                      \(2^{225}\) và \(3^{150}\)

Answer 1

\(2^{225}=\left(2^3\right)^{75}=8^{75}\) ; \(3^{150}=\left(3^2\right)^{75}=9^{75}\)

Vì: \(8^{75}< 9^{75}\) nên \(2^{225}< 3^{150}\)

Answer 2

\(2^{225}=\left(2^3\right)^{75}=8^{75};3^{150}=\left(3^2\right)^{75}=9^{75}\)

Vì \(8^{75}< 9^{75}\) nên \(2^{225}< 3^{150}\)
